Khemica, I can't imagine how you are feeling! Dialysis is a tough thing to go through, and is just as hard, in a different way, for family and loved ones. It sounds like you are considering all angles of the relationship, which should help you make some decisions. Just know that you and your fiancé's lives are not over just because of dialysis. You can have a new normal. You can still travel. It is just going to be a different normal. Things are going to take a little more work. It will be worth it, though. There is nothing that can bring to people together or tear them apart like chronic diseases.
I am not on dialysis, nor is my husband, but we are having fertility problems, as well. His sperm count is excellent, but I have had two uterine surgeries and am in my early 30's. I think there may be too much scarring for me to conceive. There are other options besides IVF. Adoption is a big one, but I can understand the heart ache of not seeing what you and your partner look like together. Another way is to adopt an embryo if you want the experience of carrying a child. This means that the fertilized eggs not used in another woman's IVF can go to you. I would check that out. It is a little cheaper than IVF. When you have "baby fever" it is hard to let go of that. I hope you can find a solution that fits you and your partner.
Please continue to reach out here. We are always ready to listen and give advice. I pray that you are your partner are soon blessed with a little one!
